  • B Inhibition in a Mouse Model of Chronic Colitis1
    The Journal of Immunology Differential Expression of Inflammatory and Fibrogenic Genes and Their Regulation by NF-␬B Inhibition in a Mouse Model of Chronic Colitis1 Feng Wu and Shukti Chakravarti2 Fibrosis is a major complication of chronic inflammation, as seen in Crohn’s disease and ulcerative colitis, two forms of inflam- matory bowel diseases. To elucidate inflammatory signals that regulate fibrosis, we investigated gene expression changes under- lying chronic inflammation and fibrosis in trinitrobenzene sulfonic acid-induced murine colitis. Six weekly 2,4,6-trinitrobenzene sulfonic acid enemas were given to establish colitis and temporal gene expression patterns were obtained at 6-, 8-, 10-, and 12-wk time points. The 6-wk point, TNBS-w6, was the active, chronic inflammatory stage of the model marked by macrophage, neu- trophil, and CD3؉ and CD4؉ T cell infiltrates in the colon, consistent with the idea that this model is T cell immune response driven. Proinflammatory genes Cxcl1, Ccl2, Il1b, Lcn2, Pla2g2a, Saa3, S100a9, Nos2, Reg2, and Reg3g, and profibrogenic extra- cellular matrix genes Col1a1, Col1a2, Col3a1, and Lum (lumican), encoding a collagen-associated proteoglycan, were up-regulated at the active/chronic inflammatory stages. Rectal administration of the NF-␬B p65 antisense oligonucleotide reduced but did not abrogate inflammation and fibrosis completely. The antisense oligonucleotide treatment reduced total NF-␬B by 60% and down- regulated most proinflammatory genes. However, Ccl2, a proinflammatory chemokine known to promote fibrosis, was not down- regulated. Among extracellular matrix gene expressions Lum was suppressed while Col1a1 and Col3a1 were not. Thus, effective treatment of fibrosis in inflammatory bowel disease may require early and complete blockade of NF-␬B with particular attention to specific proinflammatory and profibrogenic genes that remain active at low levels of NF-␬B.

Abstract DNA methylation influences gene expression and is altered in many cancers, but the relationship between DNA methylation and cancer outcomes is not yet fully understood. If methylation of specific genes is associated with better or worse outcomes, it could implicate genes in driving cancer and suggest therapeutic strategies. To advance our understanding of DNA methylation in cancer biology, we conducted a pan-cancer analysis of the relationship between methylation and overall survival. Using data on 28 tumor types from The Cancer Genome Atlas (TCGA), we identified genes and genomic regions whose methylation was recurrently associated with survival across multiple cancer types.

  • Functional Genomic Annotation of Genetic Risk Loci Highlights Inflammation and Epithelial Biology Networks in CKD
    BASIC RESEARCH www.jasn.org Functional Genomic Annotation of Genetic Risk Loci Highlights Inflammation and Epithelial Biology Networks in CKD Nora Ledo, Yi-An Ko, Ae-Seo Deok Park, Hyun-Mi Kang, Sang-Youb Han, Peter Choi, and Katalin Susztak Renal Electrolyte and Hypertension Division, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania ABSTRACT Genome-wide association studies (GWASs) have identified multiple loci associated with the risk of CKD. Almost all risk variants are localized to the noncoding region of the genome; therefore, the role of these variants in CKD development is largely unknown. We hypothesized that polymorphisms alter transcription factor binding, thereby influencing the expression of nearby genes. Here, we examined the regulation of transcripts in the vicinity of CKD-associated polymorphisms in control and diseased human kidney samples and used systems biology approaches to identify potentially causal genes for prioritization. We interro- gated the expression and regulation of 226 transcripts in the vicinity of 44 single nucleotide polymorphisms using RNA sequencing and gene expression arrays from 95 microdissected control and diseased tubule samples and 51 glomerular samples. Gene expression analysis from 41 tubule samples served for external validation. 92 transcripts in the tubule compartment and 34 transcripts in glomeruli showed statistically significant correlation with eGFR. Many novel genes, including ACSM2A/2B, FAM47E, and PLXDC1, were identified. We observed that the expression of multiple genes in the vicinity of any single CKD risk allele correlated with renal function, potentially indicating that genetic variants influence multiple transcripts. Network analysis of GFR-correlating transcripts highlighted two major clusters; a positive correlation with epithelial and vascular functions and an inverse correlation with inflammatory gene cluster.

  • Six Microsatellite Markers on the Short Arm of Chromosome 6 in Relation to HLA-DR3 and TNF−308A in Systemic Lupus Erythematosus

We investigated whether the association of HLA- DRB1*0301 (HLA-DR3) and TNF−308A with SLE could be attributed to polymorphic markers in the chromosomal region encompassed by HLA-DRB1 and HLA-C. Ninety-one consecutive Caucasian patients with SLE and 253 controls (organ donors) were typed for HLA-DRB1, microsatellites D6S1014, D6S273, TNFa, MIB, C1F2F5, and C1F3F2 and the single nucleotide polymorphism at position −308 in the promoter of TNF. The independent contribution of alleles to disease susceptibility was estimated by cross-tabulation and multivariate logistic regression. Possession of TNF−308A was associated with susceptibility to SLE (odds ratio [95% confidence interval], 3.70 [2.24–6.11]). This remained present after stratification on possession of HLA-DR3 (pooled odds ratio, 2.53 [1.37–4.70]). Stratification revealed a possible association of possession of C1F2F5*192 with protection from SLE beyond the effects of HLA-DR3 and TNF−308A.

    Extended LTA, TNF, LST1 and HLA Gene Haplotypes and Their Association with Rubella Vaccine-Induced Immunity Inna G. Ovsyannikova1,4*, Robert A. Vierkant3, V. Shane Pankratz3, Robert M. Jacobson1,2, Gregory A.

The telomeric class III region of the HLA complex harbors several genes, including lymphotoxin alpha (LTA), tumor necrosis factor (TNF) and leukocyte specific transcript -1 (LST1) genes, located between the class I B and class II DRB1 loci. Apart from HLA, little is known about the effect of this extended genetic region on HLA haplotypic backgrounds as applied to immune responses. Methodology/Principal Findings: We examined the association between immune responses and extended class I-class II- class III haplotypes among 714 healthy children after two doses of rubella vaccination. These extended haplotypes were then compared to the HLA-only haplotypes. The most significant association was observed between haplotypes extending across the HLA class I region, ten-SNP haplotypes, and the HLA class II region (i.e. A-C-B-LTA-TNF-LST1-DRB1-DQA1-DQB1- DPA1-DPB1) and rubella-specific antibodies (global p-value of 0.03). Associations were found between both extended A*02- C*03-B*15-AAAACGGGGC-DRB1*04-DQA1*03-DQB1*03-DPA1*01-DPB1*04 (p = 0.002) and HLA-only A*02-C*03-B*15- DRB1*04-DQA1*03-DQB1*03-DPA1*01-DPB1*04 haplotypes (p = 0.009) and higher levels of rubella antibodies.

  • An Upstream Open Reading Frame Regulates LST1 Expression During Monocyte Differentiation
    An Upstream Open Reading Frame Regulates LST1 Expression during Monocyte Differentiation Christian Schiller1, Carina Nowak1, Kalliope N. Diakopoulos1, Ulrich H. Weidle2, Elisabeth H. Weiss1 1 Department of Biology II, Ludwig-Maximilians-Universita¨tMu¨nchen, Germany, 2 Division Pharma, Roche Diagnostics, Penzberg, Germany Abstract The regulation of gene expression depends on the interplay of multiple factors at the transcriptional and translational level. Upstream open reading frames (uORFs) play an important role as translational repressors of main ORFs and their presence or usage in transcripts can be regulated by different mechanisms. The main objective of the present study was to assess whether uORFs regulate the expression of the MHC class III gene LST1. We report that expression of LST1 is tightly regulated by alternative transcription initiation and the presence of an uORF in the 59-UTR of transcripts. Specifically, using EGFP reporter constructs in human HeLa and HEK-293T cells and flow cytometry as well as western blot analysis we found the uORF to reduce the expression of the main ORF by roughly two-thirds. Furthermore, we were able to correlate a previously detected increase in LST1 protein expression during monocyte differentiation with an increase of transcription initiation at an alternative exon that does not contain an uORF.
